I think the theme of hardship at golf clubs has been evolving for about the past decade. This is best evidenced in looking at the waiting lists (or lack of them) and the fact that some clubs that used to be closed to visitors are now allowing some casual golf - you can now play Rye as a visitor, my club, Bearwood Lakes, opened its doors last year to help generate some extra revenue, and last time I was at Swinley, the pro told me that I could probably get a game if I rang up - it was previously only pre-booked societies.
There has been a big change in the economic landscape of golf course management over the past decade, and it can't only be blamed on the credit crunch. Clubs are struggling for membership, even exclusive ones that only 3 or 4 years ago had big waiting lists are now open for membership. Compared to 10 years ago, the situation is a complete night-and-day change. In the Reading area, clubs such as Calcot, Reading, Sonning, Henley, Goring etc all had big waiting lists but you can now get straight in. Even 3 or 4 years ago, I suspect that Worplesdon, West Hill and North Hants all still had reasonably long waiting lists - yet you can now get straight in. Similarly, you can get straight in at Hankley if single figures and wait only about 1 year if higher (Incidentally, I think Hankley is absolutely stunning - I have only played it in the past couple of years but they have had a massive tree clearance and it just highlights the most magnificent piece of heathland that I have ever seen)
The only clubs in the area that you can't get in are Sunningdale, The Berkshire, St George's Hill and Swinley, which are still next-to-impossible to even get on a waiting list. The only other clubs in the southeat that I suspect are/ may be still hard to get into are Walton Heath, Ashridge, Royal St George's, Royal Cinque Ports and Rye??
The good courses in the Bournemouth area are all now open and I can't think that there are many others in the southwest that have waiting lists of any note. In Wales, I suspect it may only be Royal Porthcawl. I would guess that some of the big names in Lancashire may still be hard and maybe Ganton, Alwoodly, Moortown, Little Aston, Royal West Norfolk, Hunstanton maybe?
I think several golf clubs will go to the wall over the next few years - mainly the poorly built/ designed courses that were built to satisfy the big demand in the 80s and 90s due to the fact that you couldn't get membership at most of the older clubs.
